DF X Series External Mechanical Self cleaning Filter
X Sub-series
Features: High Filter Area,High Flowrate,High Filtration Ratings
 
DFX series self-cleaning filter (DFX Filter for short), is the high efficiency scraping self-cleaning filter independently developed by LIVIC. Removing the impurities particles on the filter element outside by mechanical scraping, it continuously filters on-line. DFX filter is designed for fine and accurate filtration ranging from 50-500 micron. It can avoids extruding and breaking the impurities and is capable of the filtration for water and liquids of viscosity up to 800000cps. DFX filter is designed and manufactured per LIVIC's high performance, high quality and high reliability standard. It is a world-class quality filter.
 
 
LIVIC is the world leading self-cleaning filter manufacturer with its complete series scraping self-cleaning filters, which has three sub-series: DFX series, motor-driven external scraping; DFA pneumatic-driven internal scraping; DFM motor-driven internal scraping. They are good at different applcations and meet the various mechanical self-cleaning needs.
 
Working Principle
The liquid enters the filter from the inlet(1), flows through the filter element(6) from outside to inside. The filter element bottom is connected to the outlet(2), through which the liquid flows out. After the filter element captures the impurities, the cleaning action is trigger by the preset time or differential pressure value. The gear motor(4) drives the scraping blades(7) to rotate and remove the impurities on the filter element outside surface. The impurities moves off along the blades and falls down to the filter bottom. The rotating plates push the gravity impurities into the collection chamber(5). The impurities are collected at the filter bottom and in the collection chamber. The discharging valve open per the preset time and discharging the waste liquid with high impurity concentration through the drain outlet(3), the purged liquid can be reclaimed if necessary.
